Proteins Flashcards
1
Q
What makes a protein a protein?
A
The polypeptide link
2
Q
Fibrous proteins have what kind of bonding?
A
Hydrogen bonding between the N-H & C=O
3
Q
Globular proteins are coiled together why?
A
Because they need to be soluble
4
Q

A
Condensation reactions and amino acids
5
Q
Why do we have to make sure we take in amino acids
A
Because our bodies need them and our body doesn’t make them
6
Q
If R is hydrogen in a protein what is it?
A
Glycene. If R is CH3 the amino acid is alanine
